A. Warm-up: Mapping a Magnetic Field A1. The clear plastic magnetic field mapping boards have small pieces of wire that align with the local magnetic field direction. Place two mapping boards on top of the single bar magnet and observe how the wires align themselves. On your whiteboard, sketch the magnetic field lines due to a permanent magnet, including direction. B A2. A permanent magnet is illustrated at right. Using your sketch, you should be able to determine the direction of the magnetic field D at each of the points A-E. (Points A-D are in the same plane as the magnet, and E is above the magnet, out of the page.) A3. Now use the Pasco magnetic field sensor (Appendix A) to measure the magnitude of the magnetic field at these points. At which labeled point is the magnitude of the magnetic field the largest? Now look at the board with two magnets. In this case, the total magnetic field is the sum of the magnetic fields from either magnet individually. This is another example of superposition, in which individual contributions added together yield the net result. A4. What arrangement can you design to make the magnetic field equal to zero between the two magnets? List all your designs. Use the Pasco magnetic field sensor to evaluate your designs. N A5. What magnet orientations can you design to establish the maximum possible magnetic field between the two magnets? Use the Pasco magnetic field sensor to evaluate your designs.
